Letters Patent 101,521, dated April 5, 1870.

To all whom it may concern:

Be it known that I, Framers Scenes, of New York city and county, in the State of New York, have invented a new and Improved Carriage-Axle; and I hereby declare the following to be a full and exact description thereof, reference beinghad to the accompanying drawings forming part of this specification. The'nature or essence of my invention consists in making a metallic axle for carriages or vehicles the middle part of which consists of a flattened plate provided with a rib or angle piece to stifien and strengthen it.

In the drawing hereinbefore mentioned- Figure 1 is an elevation of my improved axle with a wooden stock or bolster upon it;

Figure 2 is a plan or top view of the metallic -axle;

Figure 3, an elevation of the same; and

Figure 4, a transverse section of the axle and stock.

I forge the metal axle A of iron or steel with the lib a, the whole made in one piece, the middle part of A being reduced to a flattened plate, as shown.

I form the rib a so that it shall' extend along the middle of A the top of the plate, and make it in thickness somewhat less than theplate, and in width about equal to half the same, but the precise location, width, or thickness is not material.

I also make the plate of thentxle so that it becomes thicker toward the wheel-journals and the rib,

a to taper off and become narrower-in the same part. B is a wooden stock or bolster fitted upon the metal axle, a groove being out in it to receive the rib a,so that the stock may tit closely upon the plate of the axle A and cover entirely the projecting rib. By the above described mode of construction I combine in my improved axle lightness, stiffness, and strength in a high degree, and the rib a being entirely concealed by the wooden stock B a very neat appearance is presented.

It is to be understood that I do not claim aflat axle bar strengthened by aseparate piece fastened upon it by clips or other similar device, such a construction being already in use; but

I claim as a new article of manufacture-1 A metal carriage-axle, the middle part of which consists of a flattened plate stiffened and strengthened by a projecting angle piece or rib, when the whole is made in one piece, sul'istantially as described.

FRANCIS SOHERB.
